Embodiment Construction

[0040] figure 1 An embodiment of an electric heating device is shown having a power part designated with reference numeral 2 and a control part designated with reference numeral 4 . The power part 2 and the control part 4 form a constructional unit of the electric heating device.

[0041] The control part 4 is formed externally by connecting the case 6, as in the Figure 4 Specifically shown in the diagram of the connection housing, the connection housing comprises a screening housing (screening housing) 8 (which is formed, for example, as a deep-drawn or cast metal housing respectively), a plastic housing element 10 (which is inserted into a metal housing 8) and housing cover 12. In the connected state, the housing cover 12 can be snapped onto the free flange of the sheet metal cup 8 and is made of metal so that the interior of the control part 4 is completely shielded by the metal connection housing 6 . However, the housing cover 12 can also be formed from plastic.

Abstract

The invention relates to a heat generating element, particularly to one for an electrical heating device for a motor vehicle. The heat generating element comprises a positional frame (76) and contact plates (82). The positional frame is formed in a way to make at least one PTC element (80) accommodated in receptacles (78). The contact plates abut oppositely situated sides of the PTC elements (80). Each receptacle 78 specified by a basically flat inner circumferential surface of the positional frame 76 has on oppositely situated sides at least two protrusions labelled with reference numeral 188.

Description

technical field [0001] The invention relates to a heat generating element, in particular for an electric heating device of a motor vehicle, having a position frame and a contact plate, the position frame being formed to accommodate at least one PTC element In the container therein, the contact plate adjoins two oppositely positioned sides of the PTC element. [0002] In particular, the invention relates to a heat generating element for an electric heating device of a motor vehicle, whereby the heating device has a frame forming openings on opposite sides for the passage of a medium to be heated. In the frame is arranged a layer structure that accommodates the above-mentioned heat generating elements, whereby in this layer structure, in each case, the corrugated rib elements generally adjoin in a thermally conductive manner oppositely positioned sides of the heat generating elements, so that the heat generating elements The heat generated by the heating element is regularly di...
